BeavisJem 0 Posted December 20, 2003 Do you know how to test your boost levels? 1. Start Motor 2. Move the MFA selector to "2" 3. Press and hold the MFA end button (keep holding) 4. Stop motor 5. Start Motor 6. Release the MFA end button. 7. Press the MFA End button one time. etc etc Anyways mine were about 550 - 590 idle 1640 just before redline in 3rd Couldn't rediline in 4th, no private road :roll: 1000 0 (Atmosphere- ala no boost, charger is bypassed) 1200 2.9 psi (Your charger is dead or big boost leak) 1400 5.8 psi (Your charger is about dead or big boost leak) 1600 8.7 psi (Your charger needs new apex strips or big boost leak) 1800 11.6 psi (Great for stock pulley, Probably needs new apex strips if 68mm pulley) 2000 14.5 psi (Great for 68mm pulley on stock charger) 2200 17.4 psi (Great for 68mm pulley on heavily ported charger, hold on to your ass fast!!) Just wondering if this is a boost leak, i ahve a stage 4 charger and standard pulley. Personally i feel the car is a bit slugghish compared to when i got it, might just be placebo. Any help would be great cheers BeavisJem Quote Share this post Link to post Share on other sites
steveo29 0 Posted December 20, 2003 you cant always trust the mfa..does sond a little low,you could try removing and inspecting all the boost hoses..and spray soapy water on the joins while its running and watch for bubbles..also inspect the intercooler for stone damage how many miles are on the charger? and how much before the redline is your reading..mine goes up quite alot over the last few revs Quote Share this post Link to post Share on other sites
